Martingale Dog Collar, Limited-Slip Control and Fi GPS Tracker Compatibility for Supervised Walks and Everyday Wear

This martingale dog collar combines limited-slip control and an integrated mount for a compatible Fi GPS tracker. Designed to help reduce backing out, it offers durable, comfortable construction for supervised walks and everyday wear.

Each collar is handmade to order in Willow, Alaska, using utility-grade polyester webbing, soft neoprene lining, and stainless steel hardware. Select the Fi series, width, size, and color suited to your dog and tracker.

Key Features

• Integrated tracker mount supports Fi Series 3/3+ in 1-inch or 3/4-inch widths, as well as Fi Series 2.
